GridLayoutにテキストを表示するには？

Question

私はJFrameの出力としてグリッドを持っていますが、グリッドの左にA、B、Cなどのテキストを縦に表示する方法を理解しようとしています。1,2,3など上に。

これが私の出力です： http://imgur.com/a/rDs2Y

、これはコードです：

import java.util.*; 
    import javax.swing.*; 
    import java.awt.*; 
    import java.awt.event.*; 

    public class battleShips extends JFrame{ 

/** 
* 
*/ 
private static final long serialVersionUID = 1L; 

JButton applyButton = new JButton("New Game"); 
GridLayout experimentLayout = new GridLayout(0,6); 

public battleShips(String name) { 
    super(name); 
    setResizable(false); 
} 



public void addComponentsToPane(final Container pane) { 

    final JPanel compsToExperiment = new JPanel(); 
    compsToExperiment.setLayout(experimentLayout); 
    JPanel controls = new JPanel(); 
    controls.setLayout(new GridLayout(2,3)); 

    //Set up components preferred size 
    JButton b = new JButton("Just fake button"); 
    Dimension buttonSize = b.getPreferredSize(); 
    compsToExperiment.setPreferredSize(new Dimension((int)(buttonSize.getWidth() * 2.5)+5, 
      (int)(buttonSize.getHeight() * 3.5)+50*2)); 

    //Add buttons to experiment with Grid Layout 
    for (int i = 0; i<36; i++) 
    { 
    compsToExperiment.add(new JButton("~")); 
    } 

    //Add controls to set up horizontal and vertical gaps 

    controls.add(applyButton); 

    //Process the Apply gaps button press 
    applyButton.addActionListener(new ActionListener(){ 
     public void actionPerformed(ActionEvent e){ 

      //Set up the layout of the buttons 
      experimentLayout.layoutContainer(compsToExperiment); 
     } 
    }); 
    pane.add(compsToExperiment, BorderLayout.NORTH); 
    pane.add(new JSeparator(), BorderLayout.CENTER); 
    pane.add(controls, BorderLayout.SOUTH); 

} 

private static void createAndShowGUI() { 
    //Create and set up the window. 
    battleShips frame = new battleShips("Battleships"); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    //Set up the content pane. 
    frame.addComponentsToPane(frame.getContentPane()); 
    //Display the window. 
    frame.pack(); 
    frame.setVisible(true); 
} 




public static void main(String[] args) { 
    /* Use an appropriate Look and Feel */ 
    try { 
     //UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel"); 
     UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel"); 
    } catch (UnsupportedLookAndFeelException ex) { 
     ex.printStackTrace(); 
    } catch (IllegalAccessException ex) { 
     ex.printStackTrace(); 
    } catch (InstantiationException ex) { 
     ex.printStackTrace(); 
    } catch (ClassNotFoundException ex) { 
     ex.printStackTrace(); 
    } 
    /* Turn off metal's use of bold fonts */ 
    UIManager.put("swing.boldMetal", Boolean.FALSE); 

    //Schedule a job for the event dispatch thread: 
    //creating and showing this application's GUI. 
    javax.swing.SwingUtilities.invokeLater(new Runnable() { 
     public void run() { 
      createAndShowGUI(); 
     } 
    }); 

ヘルプをいただければ幸いです！
